A propos de l'extension complète des doigts longs et des 4 derniers orteils des primates

open access: yesRevue de Primatologie, 2015
L'extenseur commun des doigts des mains et des pieds des Primates agit sur l'aponévrose digitale dorsale, mais ne peut à lui seul en assurer l'extension complète. D'autres muscles, des extenseurs complémentaires, lui viennent en aide.

Shared and divergent principles of synaptic transmission between cortical excitatory neurons in rodent and human brain

open access: yesFrontiers in Synaptic Neuroscience, 2023
Information transfer between principal neurons in neocortex occurs through (glutamatergic) synaptic transmission. In this focussed review, we provide a detailed overview on the strength of synaptic neurotransmission between pairs of excitatory neurons in

Precise Control of Drug Release in Machine Learning‐Designed Antibody‐Eluting Implants for Postoperative Scarring Inhibition in Glaucoma

open access: yesAdvanced Healthcare Materials, EarlyView.
We developed a micro‐sized, biocompatible implant for postoperative sustained delivery of anti‐fibrotic antibodies in glaucoma surgery. Machine learning‐guided optimization of polymer composition, implant geometry, and porosity enabled precise control of drug release.

Malaria disrupts the rhesus macaque gut microbiome

open access: yesFrontiers in Cellular and Infection Microbiology, 2023
Previous studies have suggested that a relationship exists between severity and transmissibility of malaria and variations in the gut microbiome, yet only limited information exists on the temporal dynamics of the gut microbial community during a ...

Bone Healing Around Implants in Normal and Medically Compromised Conditions: Osteoporosis and Diabetes

open access: yesAdvanced Healthcare Materials, EarlyView.
xx xx. ABSTRACT Osseointegration of orthopedic and dental implants is influenced by local and systemic factors, including their physicochemical surface properties and the patient's overall health status. Titanium and its alloys have been a longstanding standard for bone implants due to their innate biocompatibility and mechanical properties.

CRH receptor genetic variation in a developmental primate model relevant to the risk to develop anxiety and depression

open access: yesEuropean Journal of Psychotraumatology, 2012
Background : Using a well-established non-human primate model of anxious temperament (AT) we characterized alterations in the neural circuit that underlie the dispositional risk to develop anxiety and depression.

Organes de primates et frontières d’humanité. Les xénogreffes controversées du docteur Voronoff (1910 – 1930)

open access: yesRevue de Primatologie, 2018
The French surgeon Serge Voronoff (1866-1951) made headlines in Paris during the 1920s for his attempt to transplant primate testicles in men. The surgeon was known in Great Britain too.

Mapping the Cerebral Organoid Landscape: A Systematic Review of Preclinical 3D Models in Neuroscience

open access: yesAdvanced Healthcare Materials, EarlyView.
Cerebral organoids are transforming brain research, yet the field remains fragmented. This comprehensive systematic review maps 738 studies published between 2014 and 2024 to uncover trends, gaps, and opportunities across neuroscience. Introducing OrganoidMap—an interactive, open‐access platform to explore and compare models—this work enables ...

From Fiber Architecture to Functional Attachment: A Clinically Relevant, Mechanically Tunable Cardiac Patch

open access: yesAdvanced Materials, EarlyView.
A personalizable platform featuring a multi‐zonal cardiac patch design at clinical scale enables precise customization of fiber architecture at micro‐ and macroscale via melt electrowriting. Distinct scaffold zones support cell alignment with mechanical force transfer and epicardial attachment.

The evolution of primate vocal communication: a social route

open access: yesRevue de Primatologie, 2023
There is no doubt that different factors determine the evolutionary trajectory of a species' communication abilities. Beyond habitat, social life is likely a selection pressure.
